Unable to run on raspberry-pi arm device

[Terence Jordan]

Hi,

I am trying to use gstreamer-java on my raspberry-pi to play a video file from java.

The code works fine on my debian x64 machine.


I am using jna-3.4

The error that i am getting is when trying to call:

args = Gst.init("Swing Player", args);

gst-launch videotestsrc ! autovideosink -> This Works..

The error i am getting.

./bin/TopperDemo.sh

Hey!

I have been trying this about a year ago, I managed to play some mp3 files using gstreamer and java.

However, I am trying again now, using a new installation, gstreamer 0.10 and java 8 and I'm getting the same exception you do. Did you find any solutions for this issue?

Hi John,

Have you tried installing JNA from the repositories, or building it on
the Pi? The stack trace in the original post would suggest JNA is not
able to extract and load its native library from /tmp, either because
of permissions or because the included ARM build in jna.jar isn't
compatible with the Pi. Highly suspect this is an issue with JNA
configuration and nothing specifically related to GStreamer-Java.

Best wishes,

Neil
